SWITCH Filed-June 20, 1932 ATTORNEY Patented J l 18, 1933 UNITED STATESPATENT OFFICE PA'UK B. BROESKE, OF NORTH CANTON, OHIO, ASSIGNOR TO THEHOOVER COMPANY, OF NORTH CANTON, OHIO, A CORPORATION OF OHIO SWITCHApplication filed June 20,

The present invention relates to electrical switches, and particularlyto means for mounting an electric switch within a hollow tubular handle,such as might be used with a suction cleaner or similar apparatus,

or within a box. More specifically the invention comprises the provisionof new and novel switch-mounting means in which the switch is easilymounted and dismounted, being held in place by resilient means when innormal position.

It is an object of the present invention to provide new and novelelectrical switch mounting construction. It is a further object toprovide a; novel construction for mounting a switch within a hollowtubular member. These and other more specific objects will appear uponreading the iollow= in specification and claims and upon consi ering inconnection therewith the accompanying drawing.

Referring to the drawing:

Figure 1 is a disclosure of the present invention embodied within ahollow tubular handle which is shown partly in section;

Figure 2 is a section upon the line 2-2 of Figure 1;

Fi ure 3 is a view in perspective of the switc mounting within a hollowtubular handle, a portion of the handle being broken away to better showthe switch position therein; 7

Figure 4 shows a modified embodiment of the present invention embodiedwithin a tu bular housing which is shown partly in sec= tion;

Figure 5 is a view similar to Figure showing a still further modifiedembodiment of the present invention.

In the drawing, and Figures 1 to 3 in pearticular, an elongated hollowtubular mem= r 1 is shown provided with alongitudinab ly extendingopening or slot 2. A cover plate 3 is provided which has the samecurvature as the tubular member 1 and closes the openin 2, beingsuitably secured to the member 1 y screws4, 4 at its ends. A. conductor5 which include leads 6 and 7 is carried by the cover pie 3, beingsuitably secured 1932. Serial No. 818,155.

thereto by means includin a strain-relief member 8 and a clamp mem er 9.

The switch indicated generally by the reference character 10, includes abody 11 formed of suitable insulating material, and an actuating lever12. The switch is po-. sitioned within the member 1 in such relationshipthat the shoulder 14 on the body 11 securely seats within an opening 13in the cover plate and the lever or trigger 12 extends therethru. Thebody 11 of the switch 10 is of such height that its side wall oppositethe lever side closely approaches the enclosing tubular member 1.Between the wall and the surrounding member rubber seat 15 is positionedwhich is of such dimensions that with the switch in place and the coverplate 3 secured tothe body 1, it is compressed thereby forcing theswitch body 11 firmly against the cover plate 3 and maintaining theshoulder 14 within the opening 13. The upper wall of body 11 may beribbed, as shown at 16, so that upon the compression of member 15relative movement between the switch and the seat member is prevented,the outer surface of seat member 15 being curved and rounded so that itsubstantially conforms to the curvature of the tubular member 1.

As a precautionary 4 surroundin metallic tubular member 1. a fibreenclosing member 17 is provided which extends the length of the body111, being car ried by the seat member 15.

Referring now to the embodiment of the invention shown'in Figure 4 aswitch or a slightly modified type is shown andis se-= cured in place ina slightly diiierent man.- ner. The conductor 5 is secured to the coverplate 3 in the same manner as in the first embodiment. The body 11 ofswitch 10? is provided with a shoulder 14 of somewhat greater extentthan that in the first embodiment, a detail necessary by the differencein the actuating levers l2, 12 in the two embodiments. In the presentexemplification of the invention the body ll of the switch is providedwith a groove or channel 18 along its upper face which is undercut atits ends and which carries a flexible fiat leaf spring 19, the ends,

of which extend into the ends of the recess to I revent the dislodgmentof the member.

ith the construction asembled the spring 19 contacts the enclosing body1 and is compressed, the action resulting in the forcing of switch body11 a ainst the cover plate 3 which is itself hel in place b screws 4, 4as before. The shoulder 14 in t e opening 13 in the cover plate preventsany longitudinal movement of the switch and spring 19 prevents thedislodgment of shoulder 14 from its seat 13;

In the embodiment of the invention shown in Figure 5 the flat spring 19of the embodiment shown in Figure 4 has been replaced by a coil sprin20, the ends of which extend within the un ercut ends of the channel 18in the manner oi sprin 19. In operation spring 20 is the functionalequivalent of spring 19 and prevents the displacement of t e switch 10.

I claim:

1. In a switch mounting, a hollow member having an opening on one side,a removable cover plate closing said opening, an electric conduitcarried by said cover plate extending therethru into said hollow member,a switch positioned in said hollow member and connected to said conduitincluding a wall spaced from said enclosing member and an o eratinglever extended thru said cover p ate, and a resilient seat membercompressed between said wall and said enclosing ollow member pressingsaid switch against said cover plate,

2. In a switch mounting, a hollow member having an opening on one side,a removable cover plate closing said opening and being itself providedwith an opening, a switch including a rigid body positioned in saidhollow member and including a portion which seats within the opening insaid plate and a wall op osite said portion, and a resilientcompressible member between said wall and the surrounding hollow memberfor the purpose of holding said switch body against said cover platewith said portion in said opening.

3. In a switch mounting, a hollow member having an openingon one side, aremovable cover plate closin said opening and being itself provided witan opening, a switch including a rigid body positioned in said holortionwhich low member and including a seats within the o ening in said plateand a wall opposite sai portion, a resilient compressible member betweensaid wall and the surrounding hollow member for the purpose of holdingsaid switch body against said cover plate with said portion in saidopening, and an insulatin cover seated on said resilient com ressiglemember and extended around sai switch.

4. In a switch mounting, a hollow member having an opening on one side,a removable cover plate closing said opening, a switch ineluding a bodyand an actuating lever, said body contacting said plate an said leverextending therethru, and a com ressible member comprising a springcarrie by said body in contact with the enclosing hollow member for thepur ose of forcing said body against said cover p ate.
